Mine does the same when cold. I am changing the brakes next weekend and planned on looking around to what might be causing it. My first thought was the struts, but based on Xenocide's post, it appears it might be something else.
I'll let you know if I find anything when I look it over this weekend.
when you guys do your struts and/or springs are you replacing the rubber pads under the springs? These usually wear through by the time struts are needed, and the metal-on-metal will squeak a bit.
Just food for thought...
